The U.S.-based research arm of China's Huawei Technologies Co. Ltd. — Futurewei Technologies Inc. — has moved to separate its operations from its corporate parent since the U.S. government in May put Huawei on a trade blacklist, according to two people familiar with the matter.

Futurewei has banned Huawei employees from its offices, moved Futurewei employees to a new IT system and forbidden them from using the Huawei name or logo in communications, a Futurewei employee told Reuters on condition of anonymity. Huawei will continue to own Futurewei, the employee said.

Milton Frazier, Futurewei's general counsel, declined comment on the separation or the strategy behind it, referring questions to Huawei spokesman Chase Skinner. Skinner did not answer questions about the effort.
